This material is completely impractical; to use it, you need equipment to maintain low temperatures.
However, the superconductor material Jiang Cheng wants to research is one that can be used at normal temperature, which is known as room-temperature superconductor material.
Room-temperature superconductor material is extremely practical; it can be used in all sorts of areas—basically anywhere electricity is used.
If Jiang Cheng can research room-temperature superconductor material, it would not only significantly impact fusion reactors but also be very beneficial for him personally.
Firstly, if this material is invented, there would be no worry about the sales issue.
Just the Yan Family alone would need a lot, as various machines could use it.
As long as Jiang Cheng can manufacture it, he can sell as much as he makes, and perhaps the state would even pay to buy everything he produces.
